Fot Posted December 20, 2020 Share Posted December 20, 2020 Hello everyone, i found a flint ball in my field approximately 8 cm diameter, in Corfu island in north-western Greece, around 500 meters from the sea. I opened it and the enterior is like in the photo. Apart from the big cavity at the center, there are also many wholes around with red soil inside. Is the big cavity a fossil sponge? If yes, when is approximately dated? Thank you Link to comment Share on other sites More sharing options...

At any rate, this has no noticeable sponge anatomy (or any fossil anatomy for that matter). Link to comment Share on other sites More sharing options...
